## Background
TECHNICAL FIELD
The present invention relates to gaming machines and in particular to slant top gaming machines used to play casino-type games.
The invention has been developed primarily with reference to a slant top gaming machine and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.
BACKGROUND
The following discussion of the prior art is intended to place the invention in an appropriate technical context and enable the associated advantages to be fully understood. However, any discussion of the prior art throughout the specification should not be considered as an admission that such art is widely known or forms part of the common general knowledge in the field.
Gaming machines for playing casino-type games are typically known to be of two main configurations. One common configuration is an upright gaming machine configuration, which is generally tall and narrow and configured to sit upon a pedestal or console. Multiple displays are located in an upper portion of the machine and a user interface including the button panel and coin and/or card inserting modules, are located in a lower portion. The front portion of an upright gaming machine normally includes a vertically hinged door, which usually opens to the left. Due to it having a generally vertically extending display, a player typically stands or sits on a tall stool, when using an upright gaming machine.
Another gaming machine configuration is the slant top gaming machine. A slant top machine is generally free standing, having a lower supporting portion and an upper display portion. The upper portion includes a sloping or slanted section where a slanted primary display is housed. The primary display is generally positioned at a shorter distance above the ground, relative to an upright machine, permitting a player to sit on a chair and slide their legs underneath the primary display in a similar way to sitting at a gaming table. A user interface having the button panel and coin/card modules are located in the lower portion.
A slant top gaming machine has a number of advantages, but also a number of drawbacks. As mentioned earlier, the primary advantage to the slant top is that it accommodates a seated player in much the same fashion as a conventional gaming table, which is convenient and comfortable for the player making slant top machine ideal for extended play. The slant top also has an outwardly extending armrest section which allows the user to rest their arms and other items.
The main drawback to the slant top gaming machine is that they are normally very heavy and have a large footprint making them difficult to relocate on a gaming floor. This means that a relatively lesser number of these machines can be placed on the same gaming or casino floor space compared to an upright gaming machine. Moreover, because of their generally stout appearance they also have to be placed at the front of a gaming floor or in more open spaces, so they can be seen.
In a similar vein, due to their generally wide footprint, another problem with slant top gaming machines is that they cannot be placed on a common base directly next to upright gaming machines because of their non modular design and interference when the vertically hinged door of an upright machine is opened. More specifically, when the vertically hinged door of an upright machine is opened, it traverses laterally outwardly to foul on the side of the slant top machine. Consequently, more clearance space is required between slant top and upright gaming machines, which results in a commercially undesirable reduced game machine density on the gaming floor.
Therefore, whilst slant top gaming machines are commercially attractive because they are comfortable and used for longer periods, their limited placement on a gaming floor results in inefficient and commercially unattractive gaming machine densities.
It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative.
It is an object of a preferred form of the present invention to provide a slant top gaming machine that can be placed on a gaming floor with minimal limitations.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same elements are denoted by the same reference numerals throughout. In the following description, detailed descriptions of known functions and configurations incorporated herein have been omitted for conciseness and clarity.
The present invention relates to a gaming machine 10 of the type that is typically classified as a slant top gaming machine used to play casino-type games. As those familiar in this art would know, slant top gaming machines have an upper portion housing a main display, which is angled 0 to 45 degrees to the horizontal plane. Slant top gaming machines are considered comfortable to use making them ideal for extended period use. However, they are also relatively bulky, having wide heavy bases. This presents several problems with respect to their location on a gaming floor. This is contrary to upright gaming machines, which are more slender in appearance having a relatively smaller footprint and a generally vertical main display.
Referring to initially to FIG. 1, the gaming machine 10 of the present invention includes a cabinet 12 having an upper portion 14 and lower portion 16. The upper portion 14 houses an angularly extending primary display 18. The lower portion includes a user interface 20 having a button panel 22, hand/armrest 24, bill acceptor 26, ticket printer 28 and supplementary promotional module 30. In the embodiment shown on FIG. 1, a pedestal 32 having a relief area 34 and footrest 36 for a user's legs when seated, is also provided. As can be seen, the pedestal is generally of the same width as the lower portion.
Gaming machine 10 is used like any other type of slant top machine, whereby a user sits at the gaming machine and engages the user interface 20 to play whatever game has been programmed. It will be appreciated that in addition to the keypad and depending on the program installed, the primary display 18 may also include a touch screen portion for user interaction.
As can be seen with reference to FIG. 2, in accordance with the present invention, the maximum frontal width WL of the lower portion 16 is substantially less than the maximum frontal width WH of the upper portion 14. As is evident, the frontal profile created by the difference in frontal widths defines a clearance area 38 under the upper portion 14 on each side of the lower portion 16. The purpose of these clearance areas will now be explained with reference to FIGS. 3 to 6.
In FIG. 3, a prior art slant top gaming machine 40 is shown directly next to a conventional upright gaming machine 42. It will be appreciated that the gaming machines are shown at standard distances from each other, or pitch, as they would be on a gaming floor. As shown in FIG. 4, when the vertically hinged access door 44 of the upright gaming machine 42 is opened, it traverses laterally outwardly thereby contacting and fouling the side of the prior art slant top gaming machine 40. Therefore, without more clearance between the machines, the access door 44 is not able to be fully opened and the upright machine 42 cannot be emptied or serviced. Those familiar with the gaming industry will appreciate that, for this reason, it is not space efficient to place slant top gaming machines directly next to upright gaming machines on a gaming floor.
Referring now to FIG. 5, the gaming machine 10 of the present invention is shown located next to the same upright gaming machine 42. When in this position, it can be seen with reference to FIGS. 6A and 6B that clearance areas 38 provide enough space for the access door 44 of the upright machine to be fully opened without fouling.
Returning now to FIG. 2, it is proposed that the frontal width WL of the lower portion 16 is generally in the range of 70 to 90% of the maximum frontal width WH of the upper portion 14 and preferably in the range of 75 to 85% to provide sufficient clearance areas 38. In the illustrated embodiment, the width of the lower portion is approximately 82% of the maximum width of the upper portion. Specifically, in the illustrated embodiment, the maximum width of the upper portion is approximately 560 mm (22 inches). Similarly, it is proposed that in the illustrated embodiment, the lateral width provided by each clearance area 38 will be in the order of 62 millimeters (2.44 inches). It should also be understood that, in the illustrated embodiment, the frontal width WL of the lower portion is approximately equal to the frontal width of a conventional upright gaming machine.
As best shown in FIG. 7, in accordance with a common variation known in the art, gaming machine 10 is also adapted to include a secondary display 50, commonly referred to as a “topper”, located above the primary display 18. It should be noted that the secondary display 50 is generally vertically extending, yet maintains the maximum width of the upper portion of the cabinet 12.
A further aspect of the gaming machine 10 of the present invention is depicted in FIG. 8. To provide further alternatives for its placement on the gaming floor, the pedestal 32 is removable from the cabinet 12. In the illustrated embodiment, the pedestal is easily removable by opening the horizontally hinged access door 52 to access a pair of connecting fixing devices (not shown). Upon removal of the fixing devices, the pedestal 32 may be easily removed from the lower portion 16.
Advantageously, as shown in FIG. 9, once the pedestal is removed the gaming machine 10 can be placed on a console 54, in a similar way to the upright gaming machine 42. It should be understood that the pedestal 32 can be removed even when the gaming machine includes the secondary display 50.
To summarise the differences and advantages of the present invention, FIG. 10 shows gaming machine 10 next to conventional slant top gaming machine 40. As can been seen, the lower portion 16 is less bulky and slenderer than the conventional slant top, yet, because the upper portion retains a similar size, gaming machine 10 retains the ergonomic advantages of slant top machines. That is, a large angled primary display comfortably sitting at a lower height and an extended armrest area 24. Also, when not located on a console, gaming machine 10 provides an under machine relief area 34 for a user's legs and footrest 36 in a similar way to a normal gaming table/slant top machine.
In use, the gaming machine 10 of the present invention is used like any other type of slant top gaming machine whereby the user comfortably sits in front of the machine to begin play.
Referring now to FIG. 11, the gaming machine 10 may also be networked into a bank of machines 70 whereby a group of players can interact with a central gaming operator or display 74 such as when the game machine is programmed to play for example roulette or blackjack. As shown, each gaming machine is separated by a joiner section 72 in order to simulate a multi user gaming table. Advantageously, the modularity and reduced footprint of gaming machine 10 allows the bank of machines 70 to be built up relatively easier than prior art slant top gaming machines.
As should be now self evident, the gaming machine of the present invention ameliorates most of the disadvantages of conventional slant top gaming machines and yet retains many of the advantages in that it can be placed anywhere on a gaming floor in a similar way to an upright gaming machine, occupies a similar footprint and is similarly easy to move around. Moreover, due to its relatively slenderer appearance, more gaming machines can be placed within a given area and/or next to upright gaming machines, increasing gaming machine densities. The modularity provided by the removable pedestal removes further limitations, advantageously providing gaming floor designers with even more options with respect to their placement and configuration.
Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
